Fender Deluxe Reverb AA763 - Vibrato preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AA763 is the first version of the blackface Deluxe Reverb. Normal and Vibrato channels feed tube-driven spring reverb and optical vibrato, and a 12AT7 phase inverter drives a pair of 6V6GTs on a GZ34 rectifier for about 22 watts. It set the template for the sparkling clean tone and early breakup of later Deluxe Reverbs.
